JOHN H. COOPER, OF PHILADELPHIA, PENNSYLVANIA.

GAS-REGULATOR.

Specification of Letters Patent No. 17,671, dated June 30, 1857.

T 0 all whom it may concern:

Be it known that I, JOHN H. COOPER, of the city of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Gas-Regulators; and I do hereby declare the following to be a full,clear, and exact descri tion of the same, reference being had to tieaccompanying drawing and to the letters of reference marked thereon.

My invention relates to improvements in that class of gas regulators inwhich a valve, spring, and inverted cup are used, and my improvementconsists in so connecting the inverted cup and valve to an arm hinged tothe interior of the instrument that its sensitiveness is increased byavoiding the obj ectionable friction common to ordinary gas regulators.

In order to enable others skilled in the art to make and use myinvention I will now proceed to describe its construction and operation.

On reference to the drawing which forms a part of this specification,Figure 1 is a sectional plan of my improved gas regulator on the line 12(Fig. 2). Fig. 2, a sectional elevation on the line 34 (Fig. 1).

A is a circular casing, the interior of which I term the regulatingchamber, and from the latter proj ects another casing B the interior ofwhich I denominate the valve chamber.

On the bottom a of the regulating chamber is a circular flange 1)between which and the exterior casing A intervenes a space termed thewell for the reception of mercury or other suitable fluid. The spaceinclosed by the circular flange b communicates through an opening d withthe atmosphere.

C 1s the inverted cup dipping with its edge a short distance into thefluid in the well. This cup is securely attached to the arm D, which issecured to the shaft E, the latter being allowed to turn on the taperpoints of the op osite studs f and f which screw into the s1 es of theprojecting casing B. In the top and bottom of this casing are openings,one directly over the other and into the upper opening is screwed thenipple F for receiving the house branch or distributing pipe to theburners.

Into the under opening is screwed the coupling G and to the latter isconnected the exit pipe from the meter. This coupling projects upward aconvenient distance into the interior of the valve chamber and forms theseat for the conical valve H, which is secured by the screw h to the armD in such a manner as to be. readily and nicely adj usted, so as tocoincide with the opening of the coupling G.

To,the bottom a of the regulating chamber is attached the root of thespring I, the end of which bears against the underside of the inverted0% C. Through a boss passes the screw furnished with a hand e n andtightening nut m, the point of the screw bearing against the undersideof the spring I so that the latter may, by turning the screw in onedirection or the other, he made to bear with greater or less forceagainst the underside of the inverted cup. The top of the regulatingchamber is furnished 'with a screwed lid M so that access can beeasilygained to the interior.

The spring I is regulated by the screw K so as to furnish the requiredamount of gas to the burners. Shouldthe pressure oi gas become excessiveand consequently pass in excessive quantities through the coupling Gfrom the gas meter that excess of gas has no sooner passed through theannular opening between the valve and seat than it takes 7 effect on thesurface of the inverted cup C de resses the same and also depresses theva ve nearer to its seat and thereby contracts the annular opening,retarding the excessive flow of gas and reducing the pressure to thedesired standard and this before the excessive pressure is communicatedto the burners.

Should the burners consume more gas than the regulator was adjusted tosupply the pressure in the distributing pipe and consequently on theinverted cup becomes diminished and the cup with the valve rises by theaction of the spring I thereby enlarging the opening between the valveand seat and admitting a supply of gas equal in quantity to the excessconsumed.

It will be thus seen that a supplyof gas uniform in pressure andquantity is turnished to the burners, irrespective of the varyingpressure in the street main, or the quantity which passes into thedistributing main.

By securing the inverted cup 0 and valve H to the arm D, and hanging thelatter on the fine points of the studs 1, and f much more s'ensitivenessof action is obtained than in ordinary gas regulators, in which thevalve and inverted cup are guided by guards which produce an amount offriction detrimental to the efficient action of the instrument.

I do not desire to claim the inverted cup, spring, and valve, as suchare common to other gas regulators; neither do I desire to claim broadlythe hinging of the cup and valve to the interior of the casing, but

What I claim and desire to secureby Letters Patent is The combination ofthe inverted cup O, arm D, and valve H When both valve and cup areattached directly and permanently to an arm hinged to the interior ofthe casing substantially in the manner herein set forth, 15 and for thepurpose specified.

In testimony whereof, I have signed my name to this specification beforetwo subscribing Witnesses.
